The alarms 40107 and 50009 indicate that a limit switch has been crossed. The alarm 20005 could contain information, which helps to find the reason. Therefore you should analyse the alarm 20005 with all additional parameters. With the additional information and the alarm description perhaps you get ahead with the problem.

You can find a description about the alarms in the online help area of the Simotion Scout.

It would be also important to know in which order (sequence) the alarms arose (what was the first alarm message).

Furthermore you should check whether you have active alarms in the drive. For this you must be online with the driveby Simotion Scout.

For me is not clear what the UPS has to do with the problem. Perhaps there are not all peripheral devices buffered with the UPS.

If you get not solved the problem you can contact also the hotline for SIMOTION:Tel: ++49 (0) 180 5050 222Fax: ++49 (0) 180 5050 223New Support Request: http://www.siemens.com/automation/support-request
